e. Do not disassemble the cartridge.
f. Do not subject the cartridge to unnecessary vibration or impact. In particular, do not force down on the
photosensitive drum through the shutter found under the cartridge.
g. Do not keep the cartridge inside the machine when moving the machine. Be sure to put the cartridge in its
protective bag, or wrap it in thick cloth to avoid light.
h. Do not place the cartridge near a CRT display, disk drive, or floppy disk, as the magnetism from the cartridge can
destroy the data.
i. Keep the cartridge out of reach of children.
j. The photosensitive drum is susceptible to light, thus the presence of a shutter under the cartridge. If exposed to
strong light for a long time, the copies may start to develop white spots or vertical bands. These faults may
disappear if the machine is left at rest for some time, or the memory (cause of the faults) may remain permanently.
If you must take out the cartridge from the machine, be sure to put it in its protective bag, or cover it. Never leave it
alone unprotected.
MEMO:
If the photosensitive drum is exposed to 1500 lux (general light) for 5 min and then left alone for 5 min in a dark
place, it may recover to a level that will not cause practical problems. Nevertheless, avoid direct sunshine by all
means, which is as strong as 10000 to 30000 lux.
k. Advise the user to send all used drum unit to the designated place.
Do not throw a drum unit (used or not used) into fire. It may burst or explode.
